The August 5th event

So what happened on August 5th that caused the market for every battleground state to spike for McCain? Surprisingly, the answer is not entirely obvious. All things considered, the best I can come up with is this: "McCain makes a last-minute purchase of $6 million in Olympics ad time, topping Obama’s $5 million buy." (From thepage)In addition, Rasmussen and Zogby released polls on 8/4 in which McCain lead.

Which of these is the real market driver is a significant question for determining just how political prediction markets are going to work. Are the prices driven by those with a deeper understanding of the process, or are they merely a lagging indicator of recent poll results?
